This game is part of the Wreck Room Arcade series which consists of four different "activities". You can buy and play them separately, but they link into the same main menu - and, if you have bought them all, you get another bonus game for free (it will be unlocked after you've installed the last game).
Eight Ball Chaos is "billard light" - you don't play against an opponent, you "just" have to shoot the balls in the pockets with the corresponding color. You can get bonus points for scoring tricks, though. The game features the well-known "Monsters Inc" protagonists.
